In 1824, French engineer Nicolas Leonard Sadi Carnot – known as the father of thermodynamics – proposed what is known as the Carnot engine, the most efficient engine which is theoretically possible.

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 degrees Celsius and emanates from things like computers, cars or large ...

Researchers at the Indian Institute of Science (IISc.) and Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have cracked an age-old thermodynamic puzzle by devising a novel micro heat ...

A British engine manufacturing start-up is taking inspiration from a 200 year-old principle of thermodynamics to achieve a significant breakthrough in engine technology, one which promises a ...

THE caloric theory of heat as developed by Carnot in his famous “Reflexions on the Motive Power of Heat” (Paris, 1824) leads immediately to the correct solution of the relations between heat and ...

Prof. SUN Qingping (left) and Research Assistant Prof. LI Qiao (right), both from the Department of Mechanical and Aerospace Engineering at HKUST, demonstrate their newly developed Ti₇₈Nb₂₂ elastic ...

THE cycle proposed by Dr. J. S. Haldane (NATURE, August 29, p. 326) as a standard of comparison for steam engine performance can be shown quite readily on a temperature-entropy chart, and thus be ...

The humble air compressor is a staple of the modern workshop, underpinning everything from tire inflation to air tools, factory equipment, research gear and paint sprayers. But there's always a better ...
